Pathetic to see JW's attempting to explain their ludicrous and unscriptural, contrived and forced definitions of the meaning of 'generation', all to fit around their ludicrous and contrived 1914 chronology. In another 50 years they will still be trying to twist and rationalise 'generation' somehow to match 1914.
You have to look no further than the Matthew 1: 17 to work out how long a scriptural generation is when Jesus uttered his famous words:
"Thus there were fourteen generations in all from Abraham to David, fourteen from David to the exile to Babylon, and fourteen from the exile to the Messiah."
The average length of these 14 x 14 x 14 generations is no where near 100 years, not even half that, yet the Watchtower Society totally ignores this! Why? Because it utterly and scripturally refutes their lies.
So much for the Watchtower's arrogant boast that they are the only religion that lets the Bible interpret itself? Quite the contrary.
